Some professors make a recording of their lectures and ask students to watch this recording before class so that they can do more practice or discussion in class.

With the development of technology, teachers can use more kinds of teaching facilities. Some of them prefer to ask students to learn by themselves with the help of recordings. From my point of view, this strategy is quite useful, for it helps us save a lot of time.

First, it shortens the time used for teaching. Students are required to watch the recordings before class, then they can find out what confuses them and ask questions about these parts in class. Then during the lecture, the only thing for professors to do is answering these questions. They no longer need to waste time repeating the part that everyone understands. Thus, by doing so, teaching efficiency can be increased dramatically.

Second, the saved time can be used for discussion, which benefits a lot. In most cases, students may misunderstand parts of their lectures, and these mistakes can be exposed by discussion. Sometimes we share the same mistakes with others. If so, it will be a great opportunity for us to find out the solution together. Our ability for expression will be enhanced when we discuss a lot. Even if we comprehend everything without confusion, others can also inspire our thoughts. For instance, when faced with the same problem, others’ solutions may be more creative and simple than ours. So in both situations, we benefit from the discussion.

Last but not least, by saving time we have more chances to do some practices immediately. As is known to us, doing practices as soon as we learn something new helps us better understand the knowledge. If time promotes, we can practice a lot. When we practice in class, professors can watch our behaviors and find out whether we understand the lecture deeply. If not, they can point out our faults and repeat explaining the confusing parts again. On the contrary, however, if we do some practices after class by ourselves, we may never find our errors without guidance.

All in all, because of the reasons mentioned above, I believe this method effective.

On the contrary, is we do some practices after class, we may never find our errors without teachers’ revision.

In light of the reasons noted above, I believe watching teaching recordings is effective.
